Re: home zero gage and car zero gage?????

I dont see it being an issue on running it, as long as your careful with the runs, and use split loom...
The strand count will be different, but thats not the main issue. The problem will be that it wont be as flexible as traditional car audio wire, so it will be hard to run.

Re: home zero gage and car zero gage?????

The difference in strand count Has the biggest effect on flexibility. There are many variations of 1/0 AWG wire. Just saying "home" wire isn't telling.

Car audio wire doesn't have to have as good of insulation, the voltage is low. Whereas 600V wire has insulation that is quite different.

For example, NEC rates 1/0 ampacity based on installation (open air, in conduit, underground, etc.), based on connection method (60, 75, 90 deg C. lugs), and ambient temperature. Note that we are delivering a lot more power since voltage is higher. I can (and do) serve a 124,000 Watt load with THHN 1/0 awg at 480V 3phase, in metal conduit.
